SPECIFICATION forming part of Letters Patent No. 728,914, dated May 26, 1903. Application filed March 30, 1903. Serial No. 150,275. (No model.)

T to whont it may concern:

Be it known that I, NICHOLAS L. HEINZ, of Lasalle, in the State of Illinois, have invented certain new and useful Improvements in Apparatus for the Manufacture of Sulfuric Acid, of which the following is a specification.

The invention relates to the acid-chambers I and the dues for introducing the gases into same. The chambers are ordinarilyarranged in series with a Glover tower, and the fines for conducting the gases to the chambers enter the first chamber at the front end near the center at the top and are similarly arranged to connect the other members of the series, the several chambers and flues being extended in the same general direction, so that jets and exits of gases passing the fines enter and leave the chambers in the same general direction as that in which they pass along through the chambers. Thisbut imperfectly utilizes the chamber-space for diffusion and oxidation in the production of acid. I have provided an arrangement of the fiues relatively to the chambers whereby the gases passing in the fines enter and leave the chambers at opposite sides at different levels and in directions transverse to their general course in making passage through the chambers, the objects being to effect a greater travel of the gases in the chamberspace and a more thorough difiusion and consequent increased oxidation thereof in the chamber-space, and thus to secure an increase of acid product in any given chamber-space over the old way.

The accompanying drawings illustrate my invention by means of which the objects are attained.

Figure 1 of the drawings is a side elevation showing a fragment of two chambers in series, with the connecting-1i ues arranged in accordance with my invention. Fig. 2 is a top or plan view of the same. Fig. 3 is a transverse vertical section through the fiues at the line 3 3 of Fig. 1. Fig. 4 is a plan View showing the relation of the first chamber with the Glover tower.

In the drawings,Ais the acid-chambelyB the connecting-fines, and O the Glover tower. Instead of the fines being extended in a right line or in the same general direction with the chambers, as in the old way, they are curved outward beyond the plane of the chambers at the opposite sides, extended at an inclination, as seen in Fig. l, and then curvedinward to enter the sides of the chamber, as seen in Figs. 2, 3, and 4, at right anglesor transversely to the general direction in which the gases travel in making passage through the chambers. The front chamber is connected with the Glover tower by the fiues entering at the sides and preferably near the front end, one near the top and the other near the bottom, so as to produce jets of gases entering the chamber at right or obtuse angles to the general direction of the movement of gases throughout the chamber. The communications of the chambers with one another through the intermediate fines are similar, being from the bottom of the front chamber on one side to the top of the next chamber and from the top of the first on the opposite side to the bottom of the next, and so on, as appears by the words top and bottom, as seen on Fig. 4, where the fines between the chambers are shown. A steam-pipe b is provided in the enteringdues and curved to throw a jet of steam into the chamber in the,

same direction as that in which the flues enter the chambers. The effect is that the gases v enter each chamber at the forward end near the bottom and top at opposite sides and make exit at the rear near the top and bottom through the sides in opposite directions nearly parallel with the end walls and are diffused in upper and lower opposite currents throughout the corners of the chambers,which otherwise cannot be fully utilized for oxidizing the gases and producing acid, and the entrance and exit movements of the gases impart a slight rotation to the volume passing along through each chamber. The rotation causes the gases to travel much farther in the chamber-space, secures a better mixing of the gases with the steam-vapor, and increases the oxidation in the chamber greatly over the old way. The percentage of acid in proportion to the chamber-space is increased over the old way by the use of this means about fifty per cent.

I have shown fans D in the chambers,which are designed to be rotated in the direction of the ingoing gases and steam-jets to aid in producing the rotation of the volume of gases in the chambers; but the use of such fans is optional and may be dispensed with, if desired, without avoiding the invention. It is also optional whether one or more of the acidchambers are connected in the system.

What I claim is- 1. In an apparatus of the class described a Glover tower, an acid-chamber, and flues for conducting the gases from the tower to the chamber, said flues being arranged to enter the chamber near the front end from opposite sides, at different levels and transversely to the length of the system whereby the gases passing through the fines into the chamber are caused to enter in opposite directions, at different levels, and transversely to their general course through the chamber as specified.

2. In an apparatus of the class described a Glover tower, an acid-chamber, flues for conducting the gases from the tower to the chamber and steam-jet pipes one of each of said flues and steam-jet pipes being arranged to enter the chamber near'the front end from opposite sides, at different levels and transversely to the length of the system whereby the gases and steam passing through the flues and steam-pipes are caused to enter in opposite directions at different levels and transversely to their general course through the chamber as specified.

3. In an apparatus of the class described a Glover tower, an acid-chamber and fluesinto and from the chamber said flues being arranged to enter into the chamber at the sides near the front end and to pass out at the sides near the rear end, at different levels and transversely to the length of the system whereby the gases passing through the dues into and out of the chamber enter and pass out in opposite directions, at different levels,and transversely to their general course through the chamber as specified. v
